AUTOMOBILE BUMPER.

Application filed may 6, 2924;. Serial No. 711,369.

To all whom it may concern:

Be it known that I, JOHN Konnowsiu, citizen of Poland, residing at 432 E. 13th St. Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Automobile Bumpers. of which the following is a specification.

l his invention relates generally to bumpers for automobiles, motor trucksor like vehicles, and it has for an object to provide an improved form of resilient bumper constructed to cause any object struck to be deflectedtoward the 'side of the vehicle, in addition to having the force of the blow lessened by yielding character of the bumper.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a plan view of my improved bumper.

Fig. 2 is a front view.' I Fig. 3 is a fragmentary horizontal sectional view taken on the line 33 of Fig.

Fig. eiis a transverse sectional view taken on the line 4-t of Fig. 3.

Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 3.

As here embodied my improved bumper comprises a bar 10 which extends transversely in front of the automobile, and is adapted to be secured thereto as will be presently set forth. Formed on the front side of this bar midway between its ends is a hollow boss or 'projection'iil in which is located an expansible spring 12-which bears outwardly on a U-shapcd member 13 which straddles'the' projection 11, the latter being cut away at the sides thereof as at 14 to permit of movement. to accommodate the yoke portion of the said member. This member 13 is formed with cars 16 at the side thereof through which pass a pintle 17 on which is mounted a butter member in the form of a roller 18. Outward movement of the member 13 under the pressure of spring 12 is limited by lugs 20 on the boss which engage in openings 21 in the legs of the said member.

Projecting from the end walls-of the part 11 are the ears or lugs 25 to which are connected by the hinge pintles 26 the lugs or cars 27 on the inclined bars 28 which extend outwardly in front of the bar 10 from the centre toward the ends of the latter, these bars 28 overlapping the ends of the bar 10. Fixed atone end to projections 11 from. the boss are the fiat springs 30 which are fixed at their opposite ends in the blocks 31 which have dovetail extensions 31 engaging in complementary guide member 32 on the rear faces of the bars 28. These springs 30 serve as resilient qabutments for the outer ends of the bars which are hinged the forward ends of the arms 39 having transverse feet 40 on their rear ends adapted to be secured as by the screws to the angular brackets 41 which are fixed to the said-side frame members of the automobile. yoke member 45 extends between the arms 39 and is formed bumper to the automobile other end to the bars 28 p These blocks 37 are formed with real-weirdly projecting. hinge cars 37 to;

with pairs of lugs such as 46 on its ends v which straddle the arms and hold them rigid, these lugs being received by bolts 4:7

to the said arms. v a

In thp event of an object striking the bumper toward the centre thereof the member 13 will first yield, compressing the spring 12, and will then tend to move forward; the roller acting to direct the object toward the side and upon one of the bars 28 which latter in turn yield by swinging backward on their pivots and by their in clined position tend to,,inove the object toward the side of the automobile.

For use in removing bolts I may rovide the implement shown in Fig. 6 an which comprises the arms 50 hinged together as at '51 and formed at their forward ends and the said bar.

2., A bumper for vehicles con'iprnnng a.

with gripping elements 52, which latter are pressed toward one another by the tension- ,a preferred embodiment of my in ention it is to be understood that I do not limit myself to the precise construction herein shown, and that various changes and modifications mightbe made therein without departing from the spirit and scope of the invention as defined in the appended claims.

Having thus described my invention what I claim as new and desire to protect by Letters Patent of the United States is as follows y 1. A bumper for vehicles comprising a transverse bar, -a central bumper element yieldingly mounted on said bar, sidc bumper elements hinged at one end to said bar, and resilient bufi'er means interposed between the other ends of said side bumperelements transverse bar, a central bumper element yieldingly mounted on said bar, side bumper elements hinged at one end to said but, and resilient butler means interposed between the other ends of said sidebuniper elements and the said bar, said central bumper element having a roller mounted on the front thereof on a vertical axis. I

. 3. A bumper for vehicles comprising a transverse bar formed midway between its ends with a forwardly projecting hollow boss. a U-bracket straddling said boss, :1 spring in said boss pressing outward on said U-bracket, a roller mounted on said U-bracket, and resiliently mounted side bars extending from the said bracket along the said bar.

4. A bumper for vehicles comprising a transverse bar formed midway between its ends with a forwardly projecting hollow boss, a til-bracket, a roller mounted'on said U-bracltet, and resiliently mounted side bars extending from the said bracket along the said bar, said side bars being inclined with respect to the said bar.

5. A bumper for vehicles comprising a transverse bar formed midway between its ends with a forwardly projecting hollow boss, a- U-bracket straddling said boss. a spring in said boss pressing outward on said U-bracket, a roller mounted on said U- bracket, and resiliently nwunted side bars extending from'the said bracket along the said bar, said side bars being hinged to the said boss, and spring butter elements interposed between said side bars and the main bar.

6. A bumper for vehicles comprising a transverse bar formed midway between its ends with'a t'm-wardlv projecting hollow bossl a U-bracltet straddling: said boss :1 spring iii said boss pressing outward on said U- bracket. a rollerniounted on said U-braeket. and resiliently mounted side bars extending from the said bracket along the said bar. said side bars being hingedto the said boss. and spring butter elements interposed between said side liars and the main bar. said spring butler elements comprising: fiat springs fixed at one end to said boss, blocks to which the opposite ends of said s n-ings are fixed, and longitudinal guide members formed on the rear faces of said side. bars with which said blocks are slidably engaged.

In testimony whereof I have affixed my signature.
